What started as a simple string and pedal sales catalog has grown exponentially over the past thirty years. The early days were a time where catalogs didn't have much of a presence in the industry, but what began as a college dorm room operation grew rapidly. In 1986 we moved to a full product offering and 64-page catalog, which over the years has grown to 162 pages. Join the AMS family and get your free catalog now!
